Effect of barodiffusion on the distribution of velocity and concentration during biological fluid filtration through a cylindrical layer
The work models filtration of a biological fluid as a cylindrical layer in a stationary regime. The model takes into consideration finite compressibility and concentration expansion connected with both barodiffusion. Dimensionless complexes containing the relations between various physical parameters were distinguished. The influence of considered effects on the flow characteristics were numerically studied. The flow can be either convective or diffusive, depending on the relation between the dimensionless complexes. New qualitative regularities were distinguished in the distribution of the component concentration and flow velocity. A significant effect of the thickness of the porous cylinder wall has been shown. It was found that barodiffusion has a significant effect on the flow in the convective mode and small cylinder wall thickness.
